[0037] Specifically, the X-direction moving assembly includes an X-direction guide rail 4, an X-direction screw rod, an X-direction slider and an X-direction driving mechanism 5, wherein the X-direction guide rail 4 is fixedly connected to the side frame of the gantry fixed frame 9, the X-direction screw rod is fixedly installed on the X-direction guide rail 4, the X-direction slider is threadedly connected to the X-direction screw rod and is slidably connected to the X-direction guide rail 4, the X-direction driving mechanism 5 is connected to the X-direction screw rod to drive the X-direction screw rod to rotate, and the Y-direction moving assembly is fixedly connected to the X-direction slider; the Y-direction moving assembly includes a Y-direction guide rail 2, a Y-direction screw rod Rod, Y-axis slider and Y-axis driving mechanism 1, the Y-axis guide rail 2 is fixedly connected to the X-axis slider, the Y-axis screw rod is fixedly installed on the Y-axis guide rail 2, the Y-axis slider is threadedly connected to the Y-axis screw rod, the Y-axis driving mechanism 1 is connected to the Y-axis screw rod to drive the Y-axis screw rod to rotate, and the grinding sheet mechanism is fixedly connected to the Y-axis slider.

[0039] In a specific embodiment of the present invention, the above-mentioned grinding plate mechanism includes a grinding plate driving motor 8 and a grinding plate 7 connected to the grinding plate driving motor 8, and the grinding plate driving motor 8 is fixed on the Y-direction moving component.

[0043] Embodiment 2:

[0044] like Figure 6 As shown, this embodiment discloses a steel plate chamfer automatic grinding method, based on the steel plate chamfer automatic grinding system in the above embodiment 1, specifically, the automatic grinding method includes the following steps:

[0045] Step S1, placing one end of the H-beam flange plate (i.e., the steel plate to be polished) horizontally on the front side of the conveyor belt mechanism, and waiting for the H-beam flange plate to move toward the chamfering area under the drive of the conveyor belt mechanism (the conveyor belt drive motor drives the conveyor belt body to drive the H-beam flange plate to move).

[0046] Step S2: After detecting that the H-beam flange plate enters the chamfered area, the transverse distance sensor and the longitudinal distance sensor send the point coordinates of the four corners of the H-beam flange plate in the width and thickness directions (i.e., the width and thickness information of the H-beam flange plate) to the central control machine.

[0047] In step S3, the central control machine calculates the movement amount of the X-axis moving assembly and the Y-axis moving assembly according to the point coordinates of the four corners and the preset chamfering size (that is, the central control machine calculates the number of rotations of the X-axis screw servo motor and the Y-axis servo motor according to the point coordinates of the four corners and the preset chamfering size); and controls the movement of each X-axis moving assembly and the Y-axis moving assembly according to the movement amount (that is, the number of rotations of the X-axis screw servo motor and the Y-axis servo motor) to move the four grinding sheet mechanisms to the grinding position, and at the same time starts the rotation of the grinding sheet mechanism to perform a grinding operation on the edges and corners of the H-shaped steel flange plate.

[0048] In this embodiment, the grinding disc can increase or decrease the displacement of the edges and corners of the H-beam flange plate according to the process requirements set in the central control machine, thereby realizing the control of the chamfer size of the H-beam flange plate. On this basis, the central control motor can measure the real-time data of the external dimensions of the H-beam flange plate according to the front transverse distance sensor and the longitudinal distance sensor. Even if the external dimensions of the H-beam flange plate change, the dynamic displacement of the grinding disc can be controlled, thereby realizing the adaptive chamfering of the H-beam flange plate.
